Close Proximity Recovery

What is CPR? CPR is an altimeter based, two step parachute deployment system. Using a dual-deployment altimeter, the first chute (a small drogue) is deployed at apogee allowing for a fast but controlled descent. At a user selectable altitude the altimeter fires a second charge deploying the main chute allowing for a soft landing.

The altimeter is centrally located in a special compartment within the main airframe. The drogue chute is ejected from a split-point in the airframe just above the fin/motor section while the main is ejected at the nose cone. Both chutes are deployed using Piston Ejection System.

Just two simple yet strong anodized aluminum parts hold the altimeter and ejection charge cylinders as a self contained unit. Prep the assembly on a table, slip it into your rocket, screw the airframes together, and launch. Once assembled, the altimeter/charge cylinder assembly can be easily moved to another CPR3000 rocket, making it easy (and cost-effective, since you only need one altimeter) to fly CPR3000.

CPR3000 Improvements Over CPR2000

6061 Aluminum Threaded Airframe Couplers many times stronger

Fiberglass Altimeter and Mounting Tubes

Safety switch included and more robust (stronger switch, and 6amp rating)

Ejection Charge Cylinders included

will not short out the leads as they are hi-temp plastic

snap into holders

use e-matches (flashbulb charge holders are available at additional cos)

cannot leak ejection gas into altimeter bay

uses soft plastic caps to retain BP charge, not paper and tape.

Altimeter mounts more robust, stronger.

O-ring seals to keep ejection gasses from altimeter bay.

Much stronger mounting point for both threaded airframe coupler and fore piston.

This adapter allows you to easily install Stratologger altimeter in CPR3000 module using the hardware supplied with CPR modules. Includes one piece plywood adapter and 4 screws to attach the altimeter. All other products on the picture are sold separately.
